A lightweight utility for replacing one block with another, both during worldgen and afterward.
This mod allows modpack creators to effortlessly ban items or restrict their
usage using standard JSON files, without the need for complex scripts.

What About Block Swap?

I'm glad you asked! I made Reliable Replacer because of some of my personal frustrations with Block Swap. Here are
some reasons to consider switching!

Why Reliable Replacer?
  • Reliable Replacer is frequently updated and supports the latest versions, while as of the time of writing this, Block
    Swap is stuck on 1.20.1.
  • Live config reloading! Run /reload and see your changes instantly take place.
  • Reliable Replacer is fully server-side, so it's compatible with Vanilla clients!
  • Advanced filtering:
    • Filter swaps by biome, dimensions, placed feature, coordinates, or structure!
    • Toggle retrogen on or off per rule.
    • Toggle player placement replacing per rule.
  • Much more flexible configuration, supporting simple JSON configuration in user-defined folders and integrating with
    Cloth Config.
  • Per-rule toggleable persistence:
    • Decide if replacement blocks should inherit the properties of the old block.
  • Doesn't require any external libraries.

Migrating From Block Swap

Making the switch is easy! Reliable Replacer supports a legacy format designed to work exactly like Block
Swap's configuration.

When you first launch the game with Reliable Replacer installed, a swapper.json file will be automatically generated
in your config/reliable_replacer folder. This file uses a simple key-value pair format identical to Block Swap.

To migrate, simply copy the "swapper" block from your old configuration into this file:

{
  "swapper": {
    "oreganized:lead_door": "supplementaries:netherite_door",
    "farmersdelight:rope": "supplementaries:rope",
    "minecraft:dirt": "minecraft:stone",
    ...
  }
}

Note: Rules defined in swapper.json automatically inherit default settings (retrogen enabled, replace on player
placement, etc.). For more advanced control, use the standard rule format.

Features

A full feature list is available on
the Modded Minecraft Wiki.

For information and examples on how to use the mod, please also refer to
the wiki.

Quick-Start Example

Create a file called my_replacement.json, or whatever else you'd like, in config\reliable_replacer:

[
  {
    "inputs": [
      "minecraft:dirt"
    ],
    "output": "minecraft:diamond_block",
    "biomes": [
      "minecraft:plains"
    ],
    "min_y": "-30",
    "max_y": "64",
    "player_blocks": "true",
    "keep_nbt": "true"
  },
  {
    "inputs": [
      "minecraft:stone"
    ],
    "output": "minecraft:gold_ore"
  }
]
